iMessage for GoHighLevel agencies
Connect HighLevel to senderZ and replace Twilio-backed SMS with iMessage-first delivery. Each subaccount maps to a senderZ tenant — client data stays isolated, phone numbers stay dedicated, and your agency manages everything from one dashboard.
How it works
- Connect via OAuth. Click "Connect HighLevel" in the senderZ portal. Authorize your agency account in one screen.
- Map subaccounts to tenants. senderZ auto-discovers your HighLevel subaccounts. Each one maps to a senderZ tenant with isolated data and optional dedicated numbers.
- Add senderZ to automations. In any HighLevel automation, add a "Send via senderZ" step. Pick a template, choose channel, map custom fields.
- Replies route back. Inbound replies from senderZ appear in HighLevel conversations. Your team works from one inbox.
Use cases
Agency client messaging
Each client gets an isolated senderZ tenant with a dedicated number. Messages from Client A never touch Client B's data. Your agency dashboard shows all clients in one view.
Appointment reminders
Trigger an iMessage when HighLevel fires an appointment event. The recipient sees a blue-bubble reminder with date, time, and a reply prompt for confirmation — no app download, no email to miss.
Review request campaigns
After a service is completed, fire a senderZ message asking for a Google review. iMessage open rates make this materially more effective than email or green-bubble SMS.
What you get
OAuth connect
Authorize HighLevel from the senderZ portal. One click, no API key management, automatic token refresh.
Subaccount ↔ tenant mapping
Each HighLevel subaccount maps to a senderZ tenant. Client data stays isolated, phone numbers stay dedicated, billing stays separate. This is the Agency OS foundation.
Automation action
Add a "Send via senderZ" step to any HighLevel automation. Choose channel, pick a template, and map custom fields to variables.
Conversation routing
Inbound replies from senderZ route back to HighLevel conversations. Your team sees the full thread without switching tools.
Dedicated number per subaccount
Assign dedicated senderZ phone numbers to individual subaccounts. Clients see a consistent sender number; you manage the pool from one dashboard.
Frequently asked questions
How many subaccounts can I connect?
No hard limit on the senderZ side. Each HighLevel subaccount maps to a senderZ tenant — add as many as your senderZ plan supports. Scale plan includes 10 team members and 3 dedicated numbers; Agency OS (GA Q3 2026) adds per-client billing.
Does this replace HighLevel's built-in SMS?
It can. HighLevel uses Twilio or LC Phone under the hood for SMS. senderZ replaces that channel with iMessage-first delivery plus SMS fallback — no 10DLC, no per-message fees to existing contacts. You choose which automations route through senderZ.
How do appointment reminders work?
Create a HighLevel automation triggered by "Appointment Scheduled" or "Appointment Reminder" events. Add a senderZ step that sends a templated iMessage with the date, time, and location. Confirmation replies route back to the HighLevel conversation.
How does agency billing work?
Today, one senderZ subscription covers all subaccounts under your agency. Agency OS (GA Q3 2026) will add per-client billing passthrough — you set markup, your clients pay directly, you keep the margin.
Is senderZ on the HighLevel marketplace?
Not yet. Marketplace listing is planned for Q4 2026. Today you connect via OAuth from the senderZ portal — the setup takes under five minutes regardless of marketplace status.
